Logic to build a New Column....

Question

Hi Guys, I have sample data as below:
Name_____Time Bucket________# Count of Phone calls
Rob_______15 Minutes________ 2
Rob_______30 Minutes_________3
Rob_______1 hour____________2
Bobby______15 Minutes_______1
Bobby______1 Hour___________2
It is an example of our sales data....
Name is name of the Customer service rep
Time Bucket's are standard 15, 30 or 1 hour
# Count is the number of times that Sales Rep has made calls in that Time Bucket.
I have to build another column to calculate the total hours spent by each rep.
So should it be something like:
Select ((15 * Count) + (30 * Count) + (1* count)) Total Hours
from table1
Please Advise.
Thanks,
Kon

Hi, Kon,
Whenever you have a question, it helps to post:
(1) The version of Oracle (and any other relevant software) you're using
(2) A little sample data (just enough to show what the problem is) from all the relevant tables
(3) The results you want from that data
(4) Your best attempt so far
Executable SQL statements (like "CREATE TABLE AS ..." or "INSERT ..." statements) are best for (2).
Formatted tabular output is okay for (3). Type these 6 characters
{code}
(small letters only) before and after the tabular text, to preserve spacing.
This seems to be a job for "GROUP BY name".
If time bucket is a number (15, 30, 60), then its just
SELECT    name
,         SUM (time_bucket)
GROUP BY  name;If Time bucket is something else that represents 15, 30 or 60, then use CASE to map it to 15, 30 or 60.
From your description, it seems like the count of phone calls plays no role in this problem.
Do you need the average number of calls per hour, or something like that?
Post the information above if you need more help.
